What is TEXCA?

TEXCA (Thai expended clay aggregate)  is a kind of aggregate materials that is lightweight but higher in strength when compared to other aggregate materials. Due to its high firing temperature of 1250°C, TEXCA has the strength of ceramic but is light in weight.

TEXCA aggregate possesses unique properties such as light weight, high strength, thermal insulation, sound absorption and fire resistance.
In addition, the production process of TEXCA incorporates waste materials, making TEXCA an eco-friendly product.


Lightweight concrete products

TEXCA aggregate is versatile and can be used as reinforcement in various lightweight concrete products such as lightweight concrete panel and lightweight concrete block.

Lightweight concrete

Lightweight concrete is a type of concrete that has bulk density lower than 2000 kg/m3. Instead of limestone, lightweight concrete is typically reinforced with lightweight aggregate such as expanded clay.

TEXCA® is a kind of lightweight expanded clay aggregate that was fired at a temperature higher than 1250 °C. Due to its light weight and high strength, TEXCA® is a versatile material. It is commonly used as reinforcement in lightweight concrete products.

TEXCA®-reinforced concrete mix can be designed according to its application to have a range of density from 680 to 1850 kg/m3 as well as compressive strength from 10 to 500 kg/cm2.

TEXCA®-reinforced concrete or “TEXCA® CONCRETE” has various applications such as ready-mixed lightweight concrete, prefabricated lightweight concrete products, and concrete repair. TEXCA CONCRETE poses the following unique properties:

1.20 – 60 % lighter than conventional concrete, reducing overall structural weight and saving construction and transportation costs

2.stronger than other types of lightweight concrete such as grey CLC (Cellular Lightweight concrete and white AAC (Autoclaved Aerated Concrete)

3.better thermal insulation when compared to conventional concrete

4.better fire resistance than conventional concrete due to TEXCA’s high-temperature manufacturing process

5.better sound insulation when compared to conventional concrete

6.can contribute to LEED certification points
